'I his improve'd conveyera-nay constitute an entire conveyer or a section adapted to be interposed between other sections so that a curve or transverse deflection may be provided in a conveyer in the length thereof for convenience in placing goods upon the conveyer or removing goods therefrom.

At its ends the improved conveyer is provided with stands or frames, each of which has side bars 2 mounted in slots 3 at upper ends of legs Lwhere theysare-firmlyisecuredrhyrrivets 5.

Between the frames I extends a band lfl 'fomed 1a .qaluralitvofiinks or :plates ':2 0 having shin ge ears through which pass pins 2| so ithat *the plates 'iDI' links are pivoted .to "each other tor transverse swinging movement. Therefore, lithe band may :ex-tend in a straight line between the aemdtframes, as shown in Fig. =or be "swung transversely Ftoward one side or *the other to -dispose an end of the conveyer close to a pile of goods in a warehouse. It will thus be seen that as goods are piled in a warehouse or removed therefrom, the conveyer may be shifted to a position in such relation to the pile that goods may be easily removed from the conveyer and placed upon the pile, or removed from .the pile and placed upon the conveyer. Yokes or brackets 22 extend transversely of the band l9 over its links 2H and are formed with depending ears 23 which straddle the links, as shown in Fig. 4, and are secured thereto by bolts 24. These yokes have upstanding ears 25 at their ends through which pass pins 26 constituting pintles for rollers 21 which are spaced from each other the same distance as the rollers II. By providing the rollers IT and 21, articles may be easily moved along the conveyer. U-shaped straps or hangers 28 are secured to the plates 20 in depending relation thereto by rivets 29 and through these hangers passes a flexible strip 3llformed of spring steel or other suitable material. strip. 30 pass through the sleeves and, when the conveyer is shifted transversely, the strip slides through the hangers and thesleeves and -isv tion by tightening the set screws 15. Since the End portions of the and extending transversely thereof, hangers depending from said links, a resilient strip passing through said hangers and supported thereby, sleeves carried by said frames and extending longitudinally thereof with portions of the strip slidably passing through the sleeves, and means carried by said sleeves for engaging the strip and holding same against movement through the sleeves and maintaining the band in transversely adjusted position. I

2. In a conveyer, end frames, a band extending longitudinally between said frames and formed of v a plurality of links pivoted to each other for transverse swinging movement to adjusted posistrip 30 cannot slide through the hangers after the set screws l5 have been tightened, the length of the strip between the hangers will be shorter than the length of the connected plates 20 and the conveyer will be held in an arcuate path. The set screws may be left out of gripping engagement with the strip if desired. One of the hangers carries a set screw 3| for gripping the strip approximately midway its length and normally holding the strip in the position shown in Fig. 2, with its ends projecting a short distance out of the sleeves 14. When so secured, the strip cannot accidentally slip out of the-sleeves I 4. It should also be noted that when the'conveyer is swung transversely to an arcuate path, the pins 8 at the inner side of the conveyer may be "removed and the legs at this side of the frames shortened to impart a transverse tilt to the conveyer, the pins being then replaced to retain the legs at their shortened length.

In Fig. 5 there has been illustrated a modified construction wherein a continuous band 32 of spring steel is used in lieu of a band formed of pivoted sections or links. This band carries the brackets 22 in which the rollers 21 arerotatably mounted and ends of the'band or strippass through sleeves 33 of the stands 34. Each sleeve carries a set screw 35 for gripping the strip and holding it against movement through the sleeve after the conveyer has been swung transversely to an adjusted position and in one or both side walls of the sleeve is formed a slot 36 to receive a pin 3! projecting transversely from the strip near its end. This pin admits sliding of the strip through the sleeve in one direction, and a stop 38 secured to the strip in depending relation thereto by a fastener 39, limits sliding of the strip through the sleeve in "an opposite direction. When a strip of resilient material is used as a carrier for the brackets 22, a lower strip isnot necessary. 7

Having thus described the invention, what is claimed is:

'1. In a conveyer, end frames, a'band extending longitudinally between said frames and formed of a plurality of links pivoted to each other for transverse swinging movement to adjusted positions, rollers rotatably mounted over said links tions, rollers rotatably mounted over said links and extending transversely thereof, U-shaped hangers depending from said links, sleeves carried by said frames and extending longitudinally thereof, a flexible strip extending longitudinally of said band under the same and supported through said hangers with its end portions passing throughsaid-sleeves, and set screws carried by said sleeves for gripping engagement with the strip to secure the strip against sliding through the sleeves.

3. In a conveyer, end frames, a band extending longitudinally between said frames and formed of a plurality of links pivoted to each other for transverse swinging movement to adjusted positions, brackets over said links extending transversely thereof and having upstanding-bearings at their ends and depending earsmidway their ends straddling the links, fasteners passing through the ears and the links, rollers over said brackets rotatably carried by the bearings thereof, a strip extending longitudinally of said band, means carried by said links for slidably supporting said strip, and means carried by said frames for securing the strip against sliding movement and retaining the conveyer in transversely adjusted position.

J4. In a conveyer, end frames each having side bars, legs for the frames having upper ends secured to the-side bars, a transverse brace for the legs, a web mounted transversely between the side bars and extending downwardly below the side bars, a transverse flange, along the lower edge of said web, a sleeve extending longitudinally of each frame and fixed to the transverse brace and the flange of the web, rollers extending transversely of the frames and rotatably carried by the side bars thereof, a band extending longitudinally between said frames and secured to the webs of theframes, rollers over said band extending transversely thereof and spaced from each other longitudinally of the band, the band being flexible whereby the conveyer may be swung transversely to adjusted positions, a flexible strip carried by said band and shiftable longitudinally thereof withitsend portions slidably passing through the sleeves, and means carried by the sleeves for gripping, the strip and securing the strip against longitudinal movement with the REINHOLD A.
